Upscale images on Midjourney
This post shows the process of upscaling and zooming out an image.
After generating an image grid, use the upscale button, choosing the specific grid image you want to upscale.
The upscaled image is added to the channel. While hovering on an upscaled image, new options will become available.
In this case, the Zoom Out 2x option selected.
This will apply the selected action to the upscaled image and produce a new image grid of 4 options.
